THOMAS L. STARK, or CHICAGO, ILLINOIS.

SEWER..

SPECIFICATION forming part of Letters Patent No, 297,643, dated Aprn 29, 1884-.

Application filed December 26, 1883.

To all whom', t may concern,.-

Be it known that I, THOMAS L. STARK, re siding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sewers or Drains, of which the following, in connection with the accompanying drawings, yis a specification.

In the drawings, Figure l is a vertical section showing the relation of the main pipes, housepipes, man-hole, well, and valve with relation to each other when arranged and operating in accordance with the principle of my invention. Fig. 2 is a sectional detail showing the construction of the valve for preventing the back flow ofthewater from entering the building. Fig. 3 is a front or face view of the parts shown in Fig. 2; and Fig. 4 is a sectional detail, enlarged, showing the relation of the pipes in the lower end of the basin. Y l

Like letters of reference indicate like'parts.

The object of my invention is to provide means for preventing the setting back of the. water into the basements of buildings when the sewers or main drainage-pipes are flushed or overliow by reason of heavy storms or oth-` erwise.

A represents the street-gutter5 and B the Sidewalk.

C is a man-hole in the sidewalk, and D is a basin, into which the manhole opens, it being understood that a removablelid or cover, C', is employed for closing the said hole temporarily.

E is an overflow-pipe, communicating with the gutter and the upper end of the basin or well D. i

F is a pipe for draining the basin into the main Sewer.

Gis a pipe entering the lower part of the basin D, and also entering and draining the roof-gutter catch-basin.

H is the lower or discharging end of the pipe or system of pipes for carrying oi'f the house sewage. This pipe, as shown, enters the lower end of the basin D.

I is a valve hinged to that end of the II which enters the said basin.

.I is a rod or bar connected to the valve I, and extending upward to or nearly to the uppipe (No model.)

per end of the basin D, so as to be reached with facility by removing the cover or lid C.

K is a stud or pin extending inward from the wall of the basin D, and the upper end of the rod J has an Ieye or opening, a, therein, so that it may be suspended on the said stud or pin and be raised or lowered with facility. VIn length the rod .I is such as to hold the valve I open when the rodJ is Suspended on the said pln.

L is a pin or stud located below and Opposite to the pin K. This pin L is of such a height that the upperend of the rod J will be just underneath it when the Valve I is closed,

-thus retaining the valve iirmly in its closed position, as indicated by the dotted or broken lines in Fig. 1.

In practice I make the valve I of two metali lic pieces, b and b', the inner one of whichuis disk-shaped and adapted to Lit into the end of the pipe H, and between the plates or pieces b andrb I arrange a disk or packing lot' rubber, a', or other suitable packing material, and fasten the said plates and rubber together by means of a bolt, c, and a nut, c', all. of which is clearly indicated in Fig. 2. I also deem it best to bend the pipe F to form atrap therein, as shown at d, and to make two openings at that end of the pipe which enters the basin D, as shown at eand c. that the pipe II entersacatch-basin belonging to the system of pipes located in the building.

It will be perceived from the foregoing description and on reference to thedrawings that the valve I, when rmly closed, will prevent the entrance of any water into the pipe II, and this valve I close for that purpose whenever there are indications that the main sewer-pipes may be flushed or overflow on account of storms, melting of snow, or for other reasons. During such flushing or overlowing the water will rise in the basin D, and in case the latter becomes fullthe surplus will iiow through the pipe E into the gutter. After the water in the basin D subsides and is drained off through the pipe F, I open the valve I, by which means the 'house sewage is permitted to pass off through the pipe F into the main Sewer. It

It is to be understood IOO and valve may be kept in proper condition. l door applied to the discharging end of the pipe The drainage from the roof-gutters will serve to wash out the basin and pipe F.

In ease of wear or injury to the valve I, it may be easily repaired or renewed, and when constructed as described will be very durable, and the cleaning may be done and repairs made without the necessity of any expense or delay in removing pipes for that purpose.

The valve I, instead of being hinged, may be applied so as to slide in order to open and close the mouth of the pipe to which it is attaehed. Y

Having thus described my invention, what I elaini as new, and desire to secure by Letters Patent, is

l. The combination of the well, hole, or basin, the house-pipe II, entering the said basin, the pipe F, entering the said basin and communicating with the main sewer, a valve or H, and means for opening and closing the said Valve, substantially as and for the purposes specified.

2. The combination of the basin D, the pipes II and F, the valve I, the rod J, and nieansfor retaining it inits raised and lowered positions, the pipe or duet E, the hole or opening Gand its cover, and the roof-gutter pipe, all a1'- ranged, substantially as shown and described, with relation to eaeh other, for the purposes set forth.

In testimony that I claim the foregoing as iny own I hereto affix my signature in presence of two witnesses.

THOMAS L. STARK.
